About Nickel-Graphite Powder [-140+325]
Nickel-graphite composite powders are widely used to produce abradable coatings that improve engine efficiency by allowing rotating components to wear a precise path into a stationary seal. The -140+325 mesh cut provides a controlled particle size range that supports stable powder feeding and consistent deposit chemistry across thermal spray systems.
Graphite acts as a solid lubricant and dislocator within the nickel matrix, creating a friable, easily abradable coating structure. This makes the powder suitable for clearance-control applications in turbine shrouds, compressor stators, and labyrinth seals. The nickel content provides the necessary bond strength and erosion resistance to survive high-velocity gas flows.
Process Compatibility
This powder is typically applied using combustion flame spray or plasma spray. HVOF suitability should be confirmed based on your specific gun model and parameter set—please mention your spray system when enquiring so we can verify compatibility. The powder morphology is designed for consistent mass flow through volumetric and gravimetric feeders.
Pack Options and Handling
Standard pack sizes are 5 kg tin, 10 kg tin, and 25 kg pail. Containers are sealed to protect the powder from moisture and contamination during storage and transit. If you require alternative packaging—such as larger drums or custom-labelled containers for distributor stock—please include that in your enquiry.

Applications
Where this powder is commonly sprayed.
Turbine Shroud Abradable Coatings
Applied to stationary shroud segments in gas turbines to create a friable seal that wears in against rotating blade tips, improving tip clearance and engine efficiency.
Compressor Stator Seals
Used in axial and centrifugal compressors where a controlled abradable layer reduces back-leakage and maintains stage pressure ratios.
Labyrinth Seal Clearance Control
Coated onto labyrinth seal lands to allow rotating knife edges to cut a precise running path without excessive wear to the metallic rotor.
